Unity 5.3 stops responding when opening a scene with lightmap data

Hi, I just upgraded from unity5.2.2p4 to 5.3.0f4 and got smashed by this issue.

My scene contains the lightmap data baked with 5.2.2p4, and when opening it with 5.3.0f4, unity just stops responding. The scene file is not crashed, since the objects are

Does anyone has the same problem here??

The lightmap format has changed from 5.2 to 5.3 and need to be rebaked.
Best clear open the scene in 5.2 clear the lightmap data, open it in 5.3 and then rebake.
